I think it’d be appropriate, on a blog where posts are 50 words or less, to apply the same restriction here. That won’t leave much room to explain the mid-story comments on tales told by books, TV, film, etc., and no room for detail. Though, there's plenty of that elsewhere.
In others' words
"There is a blog called Story Comments that delivers intriguing little eggcups of quotes and observations from books, films and other media." -Jennifer Stakes
"Great review. I've also spent some time this evening looking through your blog (I would encourage others to do the same), which is very quirky and great." -Tom, on Amazon
